Question

我想在TbGridView中添加链接。点击链接显示下载选项时。

这是我的代码，

在视野中，

$this->widget('bootstrap.widgets.TbGridView',array(
    'id'=>'project-documents-grid',
    'dataProvider'=>$model->search(),
    'filter'=>$model,
    'columns'=>array(
         array(
             'class'=>'CLinkColumn',
             'label'=>'id_post_author',
             'urlExpression'=>'"/projects/documents/Download/$data->files"',
             'header'=>'Author'
         ),
         array(
              'class'=>'bootstrap.widgets.TbButtonColumn',
              'template'=>'{delete}'
         ),
     ),
));

$ data-＆gt;文件返回＆＃34; uploads / projects / filename1.png＆＃34;;

控制器路径中的功能是项目/文档/下载

在我的控制器中

public function actionDownload($name){
    $filecontent=file_get_contents('uploads/projects'.$name);
    header("Content-Type: text/plain");
    header("Content-disposition: attachment; filename=$name");
    header("Pragma: no-cache");
    echo $filecontent;
    exit;
}

但是，我有一个错误。从TbGridView下载文件的任何其他方式。

项目是一个模块，文档是控制器，下载是一个功能

Answer 1

您的操作希望您发送参数name

的值

尝试以get格式指定名称

'urlExpression'=>'"/projects/documents/Download/?name=$data->files"',

或以yii（GET）需要的方式格式化url和参数

Answer 2

// Controller Code
public function actionDownload($name = "")
{
    header('Content-Description: File Transfer');
    header("Content-Type: image/png");
    header('Content-Disposition: attachment; filename=' . $name);
    header('Content-Transfer-Encoding: binary');
    header('Connection: Keep-Alive');
    header('Expires: 0');
    header('Cache-Control: must-revalidate, post-check=0, pre-check=0');
    header('Pragma: public');
    readfile('uploads/projects' . $name)
}

Answer 3

试试这个，

<?php
public function Download($fullpath){
$filename=$fullpath;
//$fullpath like /uploads/sample.txt
$path = Yii::getPathOfAlias('webroot').$filename;
    if(!empty($path)){ 
        header("Content-type:*/*"); //for all file
        header('Content-Disposition: attachment; filename="'.basename($path).'"'); 
        header('Content-Length: ' . filesize($path));
        readfile($path);
        Yii::app()->end();
    }
}
?>

使用yii TbGridView中的链接下载文件
